strong ground motion simulation of 2017 earthquake in khorasan- razavi, iran

On april 5, 2017, an earthquake with moment magnitude of 6.1 occurred 80 km southeast of mashhad city in khorasan-razavi province (sefid sang earthquake). in this paper, in order to estimate source parameters and rupture process of the earthquake, the empirical green function (egf) method and the stochastic finite-fault (sff) techniquewere applied to simulate strong ground motion. these techniques permit estimation of parameters such as seismic moment, corner frequency, and source duration and rupture characteristics of the earthquake (miyake et al., 2000). these methods have been widely used in iran to simulate earthquakes in different regions such as 2005 zarand earthquake by zafarani (2012), 2004 firozabad kojoor earthquake by rahimi-bahoosh and hamzehloo (2011).
